That must drive your fish crazy! My fish LOVE to chase lasers!
Is that the one where you hook up an airline to it so that it makes the laser rotate 360 degrees?
Yes it is and its really cool. Turn out all the lights and you have this beam going around and around, its alot better then the first lazer light I got, the air turns a paddle wheel that turns the mirror, and you can angle the mirror so it puts the beam where you want it and so its not in your eyes.
